Insights
Percutaneous coronary intervention (PCI) with drug-eluting stents (DES) showed similar death and heart attack rates to bypass surgery (CABG) at 1-2 years. However, at 5 years, PCI with DES was linked to increased death and heart attack risks in multivessel coronary artery disease.
Area of Science:
- Cardiology
- Interventional Cardiology
- Clinical Trials
Background:
- Percutaneous coronary intervention (PCI) and Coronary Artery Bypass Grafting (CABG) are primary revascularization methods for ischemic heart disease.
- Numerous randomized controlled trials (RCTs) have evaluated PCI versus CABG in patients with multivessel coronary artery disease (CAD).
Purpose of the Study:
- To compare the long-term outcomes of PCI using drug-eluting stents (DES) versus CABG in patients with multivessel CAD.
- To analyze data from contemporary RCTs to assess the effectiveness and safety of these revascularization strategies.
Main Methods:
- A meta-analysis was conducted using data from six RCTs.
- Outcomes were compared between PCI with DES and CABG at 1-year, 2-year, and 5-year follow-up points.
Main Results:
- At 1 year, PCI with DES showed higher rates of target vessel revascularization (TVR) but lower rates of stroke compared to CABG. No significant differences were observed in death or myocardial infarction (MI) rates.
- At 5 years, PCI with DES was associated with a significantly higher incidence of both death and MI compared to CABG.
- Increased MI risk with PCI was observed in both diabetic and non-diabetic patients, while increased death risk was primarily noted in diabetic patients.
Conclusions:
- PCI with DES demonstrates comparable rates of death and MI to CABG at 1 and 2 years in patients with multivessel CAD.
- Long-term follow-up (5 years) indicates that PCI with DES is associated with an increased risk of death and MI compared to CABG.
- The findings suggest careful consideration of revascularization strategy based on patient-specific factors, particularly in diabetic individuals.
Objective:
Comparing outcomes of percutaneous coronary intervention (PCI) with drug eluting stent (DES) and Coronary Artery Bypass Grafting (CABG) in patients with multivessel Coronary Artery Disease (CAD) using data from randomized controlled trials (RCT).
Background:
PCI and CABG are established strategies for coronary revascularization in the setting of ischemic heart disease. Multiple RCT have compared outcomes of the two modalities in patients with multivessel CAD.
Methods:
We did a meta-analysis from six RCT in the contemporary era comparing the effectiveness of PCI with DES to at 1 year, 2 years and 5 years respectively.
Results:
Compared to CABG, at one year PCI was associated with a significantly higher incidence of TVR (RR= 2.31; 95% CI: [1.80 - 2.96]; P=<0.0001), lower incidence of stroke (RR= 0.35; 95% CI: [0.19 - 0.62]; P=0.0003), and no difference in death (RR= 1.02; 95% CI: [0.77 - 1.36]; P= 0.88) or MI (RR= 1.16; 95% CI: [0.72 - 1.88]; P= 0.53). At 5 years, PCI was associated with a higher incidence of death (RR= 1.3; 95% CI: [1.10 - 1.54]; P= 0.0026) and MI (RR= 2.21; 95% CI: [1.75 - 2.79]; P=<0.0001). While the higher incidence of MI with PCI was noticed in both diabetic and non-diabetics, death was increased mainly in diabetic patients.
Conclusion:
In patients with multi-vessel CAD, PCI with DES is associated with no significant difference in death or MI at 1 or 2 years. However at 5 years, PCI is associated with higher incidence of death and MI.
